怎么防守？ | T***y
发帖数: 6600 | 2 DA拿住,转攻C8,希望同伴有C KJ.需要马上立起C上的赢墩.否则,明手的C输张可以被庄
家的S垫掉.
若同伴没有C 的KJ,咋打都一样,除非,同伴的D只有Kx双张(但,同伴不该采取这么积极的
手攻)

club return may work, but it's hardly the percentage play.
it's likely partner has two tricks in majors,
so a spade return only needs partner has an ace, or club KQ if he doesn't. which covers more layouts than a club return.
for example, a possible scenario is declarer has 5512 shape, because looks like he has not much high cards for his 3H bid. In this case,
club return would be to no avail if he had the king of club.

？不是没可能，但是 anti-percentage.
不过我同意回黑桃比较好。同伴也许有ＳＡ。即使只有ＳＫ，那么是打同伴ＳＫ／ＨＡ
／ＤＫＱ，还是ＳＫ／ＨＫ／ＤＫＱ／ＣＫＪ？显然前者可能更大。

就这副牌来说，Tally的打法正好能宕4H。不过看了arrows和bucky的分析，觉得非常精
辟，回S应该是正着。北的牌型，正如bucky分析的，是6412。

东的牌是：
S: K X
H: K X X
D: K Q J X
C: K J X X
正好是arrows分析的小概率回S会失败的组合。

而转C只有特定牌张才会得利。 |
